How Can I Handle Multiple Conditions in PHP Without Nested Ternary Operators?

PHP Ternary Operator with Elseif

The PHP ternary operator is a concise way to write an if-else statement. However, it does not natively support the elseif clause.

Alternative Solutions

Instead of using a ternary operator, consider these alternatives:

• Array Lookup:
  Create an array that maps values to their corresponding strings. Access the string using the value as the key.

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

• Switch-Case Statement:
  Use a switch-case statement to handle multiple conditions more explicitly.

switch ($result->vocation) {
    case 1:
        echo "Sorcerer";
        break;
    case 2:
        echo "Druid";
        break;
    ...
}

Ternary Operator Limitations

While the ternary operator can be used for simple if-else logic, it becomes unwieldy and difficult to read when handling complex conditions. Nested ternaries are particularly problematic.

Standard Ternary Syntax

A ternary operator has the following syntax:

$value = (condition) ? 'Truthy Value' : 'Falsey Value';

It returns the first value if the condition is true, otherwise it returns the second value.

Conclusion

Array lookups or switch-case statements are more suitable for handling multiple conditions in PHP. The ternary operator should be used only for simple if-else cases where readability is not compromised.
